The following command is an example of how to start the Overcloud creation with custom environment files included:
$ openstack overcloud deploy --templates -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e ~/templates/network-environment.yaml -e ~/templates/storage-environment.yaml --control-scale 3 --compute-scale 3 --ceph-storage-scale 3 --control-flavor control --compute-flavor compute --ceph-storage-flavor ceph-storage --ntp-server pool.ntp.org
This command contains the following additional options:
--templates - Creates the Overcloud using the Heat template collection in
-e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml - The
-e option adds an additional environment file to the Overcloud deployment. In this case, it is an environment file that initializes network isolation configuration.
-e ~/templates/storage-environment.yaml - The
-e option adds an additional environment file to the Overcloud deployment. In this case, it is a custom environment file that initializes our storage configuration.
--control-scale 3 - Scale the Controller nodes to three.
--compute-scale 3 - Scale the Compute nodes to three.
--ceph-storage-scale 3 - Scale the Ceph Storage nodes to three.
--control-flavor control - Use the a specific flavor for the Controller nodes.
--compute-flavor compute - Use the a specific flavor for the Compute nodes.
--ceph-storage-flavor ceph-storage - Use the a specific flavor for the Ceph Storage nodes.
--ntp-server pool.ntp.org - Use an NTP server for time synchronization. This is useful for keeping the Controller node cluster in synchronization.
